Method and system for providing equipment rental service using biometric id card

Abstract

A portable device for biometric authentication includes a sensor configured to acquire a biometric pattern from a user who attempts to access the portable device, a biometric information storage section configured to store biometric information of a registered subscriber who has been registered to be authorized to use the portable device, a public key certificate storage section configured to store a public key certificate, and a biometric information matching section operatively coupled to the sensor, the biometric information storage section, and the public key certificate storage section. In particular, biometric information that matches the registered subscriber's biometric information is encoded and inserted into the public key certificate, and the biometric information matching section authenticates in response to determining that the user's biometric pattern acquired by the sensor matches the registered subscriber's encoded biometric information inserted in the public key certificate.

What is claimed is: 
     
         1 . A portable device for biometric authentication comprising:
 a sensor disposed in the portable device, the sensor being configured to acquire a biometric pattern from a user who attempts to access the portable device;   a biometric information storage section disposed in the portable device, the biometric information storage section being configured to store biometric information of a registered subscriber who has been registered to be authorized to use the portable device;   a public key certificate storage section disposed in the portable device, the public key certificate storage section being configured to store a public key certificate, wherein biometric information that matches or is identical to the registered subscriber's biometric information is encoded and inserted into the public key certificate; and   a biometric information matching section disposed in the portable device and operatively coupled to the sensor, the biometric information storage section, and the public key certificate storage section, the biometric information matching section being configured to reject authentication in response to determining that the user's biometric pattern that is acquired by the sensor does not match the registered subscriber's encoded biometric information that is inserted into the public key certificate.   
     
     
         2 . The portable device according to  claim 1 , further comprising a one-time password (OTP) generator. 
     
     
         3 . The portable device according to  claim 1 , wherein the sensor is a fingerprint recognition sensor, a vascular recognition sensor, a palm recognition sensor, a voice recognition sensor, an iris recognition sensor, or a combination thereof. 
     
     
         4 . The portable device according to  claim 1 , further comprising a signal transmission section configured to establish a communication tunnel to a predetermined server or terminal in response to a result of the determination. 
     
     
         5 . The portable device according to  claim 4 , wherein the predetermined server or terminal is a server or terminal for managing rental service of a public equipment. 
     
     
         6 . The portable device according to  claim 1 , wherein the portable device is implemented as a smart card. 
     
     
         7 . The portable device according to  claim 1 , wherein the portable device is implemented as a universal serial bus (USB) token or a dongle. 
     
     
         8 . The portable device according to  claim 1 , wherein the portable device is implemented as a mobile phone.
